新型太阳能选择性吸收膜的性能研究

Studies on Solar Selective Coating on the Aluminium Surface

本文介绍了一种新型太阳能选择性吸收膜(简称85-A膜)。文中详述了该种膜层的制作工艺及光学特性,列出了它的吸收率α_S、法向热发射率ε_n等参数并与国外有关文献进行了对比。最后提供了该种膜层在自然环境中试运行后的稳定性数据。

A chemical reaction technique has been developed todeposit selective coating of solar absorptance 0.94 and thermal emittance (at 85℃) 0.17 on aluminium surface Outdoor exposure and accelerated humidity test show good environmental stability to the selective coating on aluminium surface. The authors expound the characteristics of the coating on the composition and structure. Although theoretical in nature, the present paper demonstrates that 85-A coating is an excellent, stable and cheap solar selective coating.
